DOI = Digital Object Identifier

What is a DOI?

A DOI is a digital object identifier – a unique alphanumeric code that gives a persistent link to the web location for an electronic item. DOIs are commonly seen on current electronic journal articles, but are also often included in the print version of the article.

2. DOIs are often included in database records. If you're searching a library database like Academic Search Complete, and if a DOI is assigned to an article, you will find it in the database record for that article.

4. DOIs may also be found in the bibliography of an article. If you find a DOI in a bibliography and want to find the actual article (or further citation information), you need to use a DOI resolver (see:http://dx.doi.org ).
